I. HLGIP FINGL GASTER FOR TRUNKS.

Iva- 23,672. Patent ed Apr. 19, 1859;

ISAAC I-I. GIFFING, OF NE YORK, N. Y.

MODE OF ATTACHING GASTERS TO TRUNKS.

Specification of Letters Patent No. 23,672, dated April 19, 1859.

T 0 all whom it may concern:

Be it known that I, Isaac H. GIFFING, of the city and county of New Yorkand State of New York, have invented a new and Improved Caster forTrunks or Boxes; and I do hereby declare that the following is a fulland exact description, to wit:

The nature of my invention consists in providing a suflicient spacebetween the plate and roller so that a band or strap of metal. (such asis now in use for strengthening trunks or boxes) may be passed. freelybetween the plate and roller, also making a flange continuously alongthe whole length of both sides of the plate in order to prevent theplate from twisting and also for the purpose of additional strength.

To enable others skilled in art to make and use my invention, I willproceed to describe its construction and operation.

I take a plate of iron or other strong metal about of an inch inthickness about 3 inches long and about 2-1- inches wide. I then marktwo parallel lines along said plate lengthwise about of an inch fromeach edge see drawing No. 1. I then bend the plate at right angles alongboth lines and in the same direction so as to form a flange about of aninch high on both sides (or edges). I then mark off a line about an inchfrom one end and sloping downward toward the back of the plate so as toleave a flange of an inch high at one end and of an inch high at theother, see drawing No. 2. I then cut or file both flanges according tosaid sloping lines and file the highest part of the flange circular atthe end, see drawing No. 2. I then drill two or more holes in the centerpart or back of the plate (for the purpose of fastening it on the trunkor box). I then drill a hole through the highest part or end of bothflanges near the edge and so as to raise the roller from the back of theplate a sufficient distance to allow the strap or band (beforementioned) to pass along between the two flanges and also beneath theroller and between it (the roller) and the plate freely, the rollerbeing placed between the flanges so as to project beyond the edges ofthe flange a suflicient distance. I now pass a strong Wire through thetwo flanges and roller, riveting both ends of said wire firmly, seedrawing ITO. 3, or I may cut the plate of iron aforesaid in proper shapeand then bend the flanges or else I may mold and cast the plates in theshape or form all as before described. The before mentioned dimensionsare to be varied according to the size or strength re quired. The mannerof using said caster is, to rivet, nail or screw the plate (through theholes in the back) on the trunk or boX then pass the strap or handbetween the flanges, beneath the roller and between that and the plate,then bend the strap up to the side or end of the trunk and fasten therefirmly by nailing or screwing or they may be both fastened together atone time.

I do not claim the roller or strap separately as they have been used 011trunks for many years.

What I do claim is,

The method herein described of constructing and attaching casters totrunks.
